This week on Ask Lifehacker we're debating the feasibility of Google's futuristic augmented reality glasses, protecting ourselves from hacks and viruses, blocking porn in every possible way, and fitting our big hard drives on small SSDs. Also, we take a look at a few downloads that can turn your diet and exercise routines into games, make Windows 7 feel like new, and turn the pages of PDF documents with your face. It's an action-packed episode this week, so come check it out!

Sorry for the audio issues last week! We have a new setup now and things should only improve going forward.

News and Discussion

This week Adam Pash is out but we're joined by our fellow writer Alan Henry.

00:57 Credit Card Hack If you haven't been living under a rock, chances are you heard about the credit card hack that occurred a little over a week ago, compromising 1.5 million card numbers. On the podcast we go over how bad the hack was and what you should do to stay safe. Basically, the answer is not much more than what you normally do: just check your bank account regularly and report any suspicious activity.

On Friday, March 31st, news broke that credit card processor Global Payments suffered a massive…

03:19 Google GlassGoogle's Project Glass is a concept for location-aware, connected glasses that help you communicate with others, get directions for where you're going, and do pretty much anything a smartphone can do without obstructing your vision. They don't currently exist, and would rely on a cellular carrier that's fast and functional (imagine that) to work well, but are definitely an interesting idea for the future.

05:45 HD VoiceHD Voice, which I mistakenly called HD Audio in the podcast, is a sort-of-new technology coming to cellphones that provides high quality audio when you talk. (You know, audio you can actually understand.) Right know it is only available on Sprint's HTC Evo 4G LTE, is expected to reach many more phones as the year progresses.

As people increasingly abandon voice calling for texting and emailing, audio quality has been a bit …

07:28 Internet Explorer Is the Best Browser for Battery Life It turns out that if you want to eke out the most battery life from your laptop while browser, you want to use Internet Explorer. While it's not everyone's favorite browser, Microsoft has been making notable improvements over the years. If you're just doing basic browsing and longevity is paramount, it's worth keeping it around as a backup measure.

We regularly test the four most popular browsers for speed, but what about battery life? If…

09:03 A New Mac Virus Mac Malware is back! Apple actually responded to the most recent virus targeting about 600,000 people on the OS X platform, so it seems they're finally taking these issues seriously. The virus connects victims to a botnet without their consent. You can learn how to stop it here.

There's a new Mac trojan that's been floating around, and it's terrifying everyone.…

Questions and Answers

Each week we answer five questions from readers and listeners. Here's what we tackled this week.

11:24 Is upgrading to an SSD worth it, and how can I fit everything on a smaller drive?? Yes. We all agree that solid-state drives are worth the money. I even believe that their limitations are a good thing. Downsizing your data isn't always easy, especially if you're coming from a large drive, but you can replace your optical drive with an SSD if you'd prefer to lose your disc reader and writer instead of all that space you've got. If you're simply making the upgrade, you really just have to look at what you can move to an external drive and what has to stay on your boot disk. So long as you don't have a large music and video collection you need to have on your computer at all times, downsizing is pretty simple. If you can have a second hard drive, however, that is ideal. (Also, if you're a Windows user, follow these instructions to make the transfer easier.)

Installing a solid-state drive is one of the best upgrades you can make to your computer, but…

By the way, if you're thinking about upgrading to an SSD, today Newegg is offering a 120 GB OZC Vertex 3 for $110 with coupon EMCYTZT1426. (I'm not sure how long the deal actually lasts, but it was in today's deals newsletter so I figured it was a timely mention.) I've been using OCZ Vertex SSDs for years and they've been fast without any trouble. I've also had good results with Corsair SSDs, but the OCZ drives have always been cheaper. Most SSDs are going to be a huge upgrade regardless, though, so any well-reviewed brand should make for a huge jump from a standard hard drive.

14:39 Is there a good offline maps app for Android? (Specifically, on a rooted Nook Color.) You actually have a lot of options:

17:01 How can I block all porn from my network and devices from a tech-savvy individual? If you listen to this question on the podcast, it's pretty clear this tech-savvy individual is smart enough to get around pretty much any blocking method. We don't know why the caller wanted to block porn, and who the porn addict is, so it was also difficult to prescribe a solution for that reason. We felt the best option was to try as many blocking and deterrent methods as possible and continuously reset them every time they're taken down. While this won't keep the tech-savvy person away from the porn they desire, it will make getting that porn pretty annoying. Hopefully the persisting difficulty will wear them down.

So what are the methods to employ? Parental controls are an easy one. Editing your hosts file is another, so that visiting porn sites will redirect the user to a genital-free page. (This hosts file prank is a good place to start if you want to know how to do that.) You may also want to look at turning OpenDNS into a family-friendly filter.

You can spend hours figuring out how to lock down every browser in the house to prevent the…

But if you're dealing with a seriously tech-savvy minor who has an undying affection for pornography, a technical solution is probably not the answer.

23:00 If I update my unlocked and jailbroken iPhone, will it reset the unlock? Yes. Whenever you update iOS, it'll reset your jailbreak and unlock. The only exception is if you purchased a carrier- or Apple-provided unlocked phone, in which case your unlock will not be reset during an update. Jailbreaks, however, will always be reset. It's one of the reasons you may not want to jailbreak. But if you do, setting up PKGBackup beforehand can make the restoration process a lot easier.

Wouldn't it be great if iOS fully backed up your data, and did so wirelessly and…

25:44 Is there a way to transfer my Instapaper archives to Readability? Nope! Well, sort of. Whitson switched to Readability recently after writing this comparison of the three main article archiving services and found that transferring Instapaper over wasn't the easiest of options. Although we haven't tried it readability_importer might be able to help. We discuss some other semi-options on the podcast as well, but that looked like the best. If you're moving from Read It Later to Readability, however, you can use this.

Chances are, you stumble upon a lot of articles during the day that look interesting, but that you…

28:24 UPDATE: An easier way to install OS X Lion on an Old MacBook On episode 003 a listener asked how they can install OS X Lion on an old MacBook that Apple doesn't support. We gave a complicated answer, but another podcast listener called in with a simpler solution: install it on a Mac that is supported, clone the installation to an external drive, then clone that external drive back to your unsupported MacBook.

This week on Ask Lifehacker we're not talking about the new iPad, but what we'd buy…

Downloads of the Week

Each week we talk about our favorite downloads. Here are our picks for this week.

30:07 Crashplan If you're listening to the Lifehacker Podcast, you probably already back up your data. I mean, at this point it's a little ridiculous if you don't because it's just so easy. Crashplan is an app for multiple platforms that makes it super simple to not only backup locally but also keep a backup remotely. That remote backup can exist in their cloud service or you can just send it to a hard drive you have stored somewhere else. It's remarkably versatile and only costs you if you back up using their storage.

You should back up your hard drive. You've heard it a million times, but most people…

33:13 Windows "7.5" Last week, Whitson invented Windows 7.5. By that, I mean he realized that Windows 8 isn't really a vital upgrade an $100 of great apps could provide better functionality right now. Check out his post to learn more about the options and how you can roll your own Windows 7.5.

Every few years, a new version of Windows comes out with some decent, but minor upgrades and a $100 …

35:51 Instagram for Android Instagram, the popular social camera app, finally came to Android but Alan wasn't impressed. Nonetheless, if you've long been jealous of iOS users for their ability to easily share faux-vintage photos with the service, now you can join in on the fun. If not, there are plenty of great Android alternatives.

Android: Instagram, the popular photo sharing app previously only available for iOS users has…

38:13 MagicReader for iPad MagicReader is a PDF reader for iPad. It works like pretty much any PDF reader except for one thing: when you turn your head, it turns the page. Basically, MagicReader tracks the motion of your face so you can flip through a document without using your hands. This is exceptionally useful if you're eating and your hands are too messy to touch your iPad.

iPad: You probably bought an iPad with idea that you'd have your grubby hands all over it,…

39:37 Fitocracy (and More) Fitocracy (Web, iOS) and SlimKicker (Web) are both apps that turn your exercise and diet into games (respectively). If you're having trouble sticking with either routine, it's likely because you're not seeing quick rewards from the work that you're doing. Turning your diet and exercise into games helps you feel more accomplished.

Please keep your questions as brief as possible. This means about 3-5 sentences for emails and 30-60 seconds for calls and videos. Your questions can be specific, but broader questions are generally better because they'll apply to more people. For example, "how can I breathe new life into my old PDA?" is much better than "what can I do with an old HP iPAQ 210?" Either way, we look forward to hearing from you!
